BnH 54H kkH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
kk = source note number: 00H-7FH (0-127)
• A Note-on received immediately after a Portamento Control
message will change continuously in pitch, starting from the pitch
of the Source Note Number.
• If a voice is already sounding for a note number identical to the
Source Note Number, this voice will continue sounding (i.e.,
legato) and will, when the next Note-on is received, smoothly
change to the pitch of that Note-on.
• The rate of the pitch change caused by Portamento Control is
determined by the Portamento Time value.
• Not received when MIDI “Rx” part parameters is “O.
• Not received when the “Other CC” parameter of the MIDI “Rx
Event” group is “O
Example 1.

90 3C 40 Note on C4 C4 on
B0 54 3C Portamento no change (C4 voice still
sounding)
Control from C4
90 40 40 Note on E4 glide from C4 to E4
80 3C 40 Note o C4 no change
80 40 40 Note o E4 E4 o
Example 2.

Controllers is received.

**NRPN**
The NRPN (Non Registered Parameter Number) message allows an extended
range of control changes to be used. On the BK-9, NRPN messages can be used to
modify sound parameters, etc.
To use these messages, you must rst use NRPN MSB and NRPN LSB messages
to specify the parameter to be controlled, and then use Data Entry messages to
specify the value of the specied parameter. Once an NRPN parameter has been
specied, all Data Entry messages received on that channel will modify the value
of that parameter. To prevent accidents, it is recommended that you set RPN
Null (RPN Number = 7FH/7FH) when you have nished setting the value of the
desired parameter. On the BK-9, Data entry LSB (Controller number 38) of NRPN
is ignored, so it is no problem to send Data entry MSB (Controller number 6) only
(without Data entry LSB).
On this instrument, NRPN can be used to modify the following parameters.
